SPRING-WHEEL.

Specification of Letters Patent.

Patented Jan. 20, 1914.

Application filed April 12, 1913. Serial No. 760,788.

To all whom it may concern:

Be it known that we, GLos'rnr. J. (iamnrrr and HERBERT C. GARRETT,citizens of the United States, residing at Richmond, in the county oflVayne and State of Indiana, have invented certain new and useful.Improvements in Spring-lVheels; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention comprehends il'nprovcments in spring wheels and relatesmore pa 1'- ticularly to those of the type wherein the folly issupported by a plurality of cushioning members.

The, primary object of the invention is to provide a spring wheel whichshall be of extremely simple construction, cheap to manufacture, andvery strong and practical.

Another and more specific object of the invention resides in theprovision of a wheel of this nature having a folly which is supported ba plurality of expansive swings and a plurality of resilient blocks,which latter are carried upon the extremities of the spokes.

With these and other objects in view, as will become more apparent asthe description proceeds, the invention consists in certain novelfeatures of construction. combination, and arrangement of parts, as willbe hereinafter described and claimed.

For a complete umlersta-nding of our invention, reference is to be hadto the following description and accompanyingdrawings, in which,

Figure 1 is a fragmentary side elevation of our improved spring wheel,one of the side plates being partly broken away, Fig. 2 is a transversesection taken on the plane of line 2--2 of Fig. 1, and, Fig. 3 is asimilar view taken on the plane of line 3 3 of Fig. 1.

In the following description and accompanying drawings, similar partswill be referred to and designated by like characters of reference.

Referring in detail to the drawings by numerals, 5 designates the hub, 6the spokes, 7 the felly, 8 the rim, and 9 the tire of our improvedspring wheel. A block 10 is positioned between each pair of spokes andengages lugs 11 formed thereon. These blocks are situated near the outerextremities of the spokes and have their outer faces recessed, as

indicated at 12, to provide seats for the expansive spiral springs 13,which bear at their outer ends against the inner face, of the felly 7.To prevent the springs moving relative to the folly, we provide lugs 14:which are mourned upon base plates 15 and the latter are secured inrecesses formed in the folly. 'lhe lugs extend into the coils of thesprings and by engaging the same prevent a movement thereof relative tothe felly. To provide further cushioning means for the folly, we employa. plurality of resilient blocks 16 which are preferably formed ofrubber and which are interposed between the extremities of the spokesand said folly. A U-shaped frame 17 is secured to the end of each spokeand embraces a pair of blocks 16 for the purpose of holding the same inproper position. Stop members 18 a re secured to the felly by means ofthe base plates 15) and one of these lnelnbers projects between eachpair of resilient blocks and prevents a circumferential movement of thetelly relative to the spokes. It is to be noted that the cushioningblocks extend beyond the U-shaped frame and that the stop members 18terminate short of said frame so that the proper spring action of thewheel is not interfered with.

For the purpose of holding the blocks 10 and 1G and the folly 7 againstlateral movement relative to the spokes and hub, we provide annular sideplates 20 and secure them upon opposite sides of the wheel by means ofthe bolts 21 which extend through the spokes (3. These plates lic flushwith the sides of the spokes and with the flanges formed upon the blocks1.0 and extend outwardly to with in a short distance of the ribs orflanges 22 formed upon the rim 8. it will be noted by reference to Figs.2 and 3, that these side plates do not interfere with the contractionand expansion of the springs and resilient blocks, but by engaging thelatter, serve to hold them against lateral movement. These plates alsoact as a brace for the felly and prevent it moving out of properalinement with respect to the remaining portion of the wheel.

From the foregoing description taken in connection with the accompanyingdrawing, it will be seen that we have provided an OK tremely strong anddurable spring wheel which may be readily assembled and which willeffectually absorb the shocks and jars incidental to rough roads. Byremoving either of the. side plates 20 the important parts of the wheelare made easily accessible and they may be quickly removed and replacedby others if desired.

It is to be understood that while we have shown and described thepreferred embodiment of our invention, we do not wish to be limited tothis exact construction, combination, and arrangement of parts, but maymake such changes as will fall within the spirit and scope of theinvention.

Having thus described our invention, what we claim is:

l. A spring Wheel including a hub, a plurality of spokes radiatingtherefrom, a felly, va U-shaped frame secured to the extremity of eachspoke, a pair 01": cushioning blocks secured Within each of the U-shapedframes, said blocks extending beyond the frames and engaging the telly,stop members carried by the felly and projecting between each pair ofblocks to prevent a circumferential movement of the telly relative tothe spokes, and

side plates rigid with the spokes and extend ing outwardly intoengagement with the sides of the cushioning blocks and felly.

2. A spring 'Wheel including a hub, a plurality of spokes, a telly,blocks positioned between the spokes, a plurality of springs engagingsaid blocks and felly, a pair of cushioning blocks secured to the outerend of each spoke and bearing against the telly, stop members carried bythe telly and projecting between each pair of cushioning blocks forpreventing a circumferential movement of the felly relative to thespokes, and side plates secured to said spokes.

In testimony whereof we affix our signatures in presence of twowitnesses.
